Elecrow nRFLRCC68 Wireless Transceiver Module w/ nRF52840 & LLCC68
The Elecrow nRFLRCC68 is a dual-chip wireless transceiver module integrating the Nordic Semiconductor nRF52840 MCU and Semtech LLCC68 LoRa radio, supporting LoRaWAN Class A/B/C, Bluetooth 5.3, Zigbee, and NFC for versatile, long-range IoT deployments.
Features
- Dual-Core Wireless Architecture: Combines Nordic Semiconductor nRF52840 Cortex-M4F MCU with Semtech LLCC68 LoRa transceiver for multi-protocol flexibility.
- Extended Sub-GHz Range: Operates on 850-930 MHz ISM bands with +20 dBm Tx power and -125.5 dBm sensitivity for links up to 10 km.
- Ultra-Low Power Operation: Achieves a deep sleep current of just 5µA, ideal for battery-powered remote sensor nodes and trackers.
- Multi-Protocol Radio Stack: Supports Bluetooth 5.3, Bluetooth Mesh, Zigbee, Thread, NFC, and LoRaWAN for diverse network topologies.
- Developer-Ready Interfaces: Features built-in AT command firmware over UART, plus SDK access for custom nRF Connect/Zephyr RTOS development.

The Elecrow nRFLRCC68 module delivers a consolidated wireless solution by pairing the processing capabilities of the Nordic Semiconductor nRF52840 SoC with the long-range LoRa performance of the Semtech LLCC68. This integration provides a robust platform for developers building complex IoT endpoints that require both local mesh connectivity (via BLE/Zigbee) and wide-area backhaul (via LoRaWAN). The nRF52840 handles application logic, secure Bluetooth pairing, and network stack management, while the LLCC68 transceiver handles efficient, long-distance sub-GHz communication with a high link budget.
Engineered for low-power field deployment, the module operates from a 1.8V to 3.7V supply and maintains full functionality across an industrial temperature range of -40°C to +85°C. Its compact 20×20 mm form factor incorporates a crystal oscillator, RF matching network, and a chip antenna (or provision for an external antenna), making it suitable for space-constrained designs. The included AT command set allows for rapid prototyping and configuration of LoRa spreading factors, bandwidth, and Bluetooth advertising parameters without deep firmware development.
